Propagation
Seeds require scarification by nicking the seed coat and soaking in water for 24 hours prior to sowing.
Stratify fresh seeds for 2 to 3 months at 5ş C (41şF) then sow in spring and maintain a temperature of 12ş to 15ş C. (55ş to 59ş F).

Note:
Care should be taken when selecting a sight as the tree has vigorous roots that can lift concrete and block drains.
